The genetic variabilities of second chromosomes of Drosophila melanogaster concealed in Busan natural and experimental populations have been analyzed by the Cy//Pm method. The experimental population was composed of D. melanogaster which had the lethal-free second chromosome, collected Sasang natural population in 1982. The frequencies of deleterious genes were estimated to be 14.3∼25.4% in Busan natural population and 26.5∼27.2% in experimental population. The allelism rates in lethal genes isolated from the natural and experimental populations were calculated to be about 0.76% and 9.76∼14.17%, respectively. The value of elimination by the frequencies of deleterious genes and allelism rate was 0.0106and the effective population size estimated to be about 430 flies at the 6570 days population.

We investigated the effects of hypothetical deductive experiment on students' views about the nature of science (NOS). Participants were 212 eighth graders from a middle school and they were assigned to a control group and an experimental group. Students of the control group did guided experiment in small group and students of the experimental group did hypothetical deductive experiment in small group. The results revealed that both students of the control group and the experimental group possessed similar views about NOS in a pretest. But the experimental group exhibited more sophisticated views about the theory of dependance of observation, scientific reasoning and hypothesis in the posttest. Students who used mainly surface learning strategy within the experimental group exhibited more sophisticated views about hypothesis in the posttest. On the other hand, students who used mainly deep learning strategy within the experimental group exhibited more sophisticated views about the theory of dependance of observation, scientific reasoning and hypothesis in the posttest.

The purpose of this study is to discover the effects of Reality Therapy group program on leadership life skills, sociality, and classroom unity of elementary school children. The objects of this research are the 34 elementary school children at the K elementary school in the S area of Kyunggi-do, and randomly divided into two groups. Scientific methods are employed to test a Reality Therapy group program as a treatment for elementary school children to increase their level of leadership life skills, sociality, and classroom unity. For this study, one experimental group and one control group, composed of 34 students in total, are organized and treatment is conducted on these groups. The SPSS 12.0 statstics program is employed to analyze the questionnaires of both-test. Mann-Whitney U and Multiple Linear Regression test are used to analyze the result in order to verify the differences between experienced group and controlled group of pre-test scores within the groups. First, the statistics show a difference in leadership life skills factors(p<.001) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the leadership life skills. These statistics prove that experimental group has higher leadership life skills than the other group. Second, the statistics show a difference in sociality factors(p<.01) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the sociality. These statistics prove that experimental group have higher positive sociality than the other group. Third, the statistics show a difference in classroom unity factors(p<.001) between the experimental group and the control group. The Reality Therapy group program is a significant predictor of the classroom unity. These statistics prove that experimental group have higher positive classroom unity than the other group.
